This was an interesting read.

​It may be out of context for the filtering system (or it may not be)
however, some kind of a weighted mechanism can be implemented in order to
reduce the effect of temporary fluctuations or changes in the traffic.
Since these changes do not last long, they must be ignored and filtering
rules should not be installed for these.​ Otherwise, rules will be
installed only to be removed moments later.

Just a thought.
